As the Sim Eternal City Framework continues to grow and refine, the language we use must evolve to match the depth of our architectural and civic vision. Our goal has always been to design a system that is not only highly functional but also deeply human-centered and emotionally resonant.

To better reflect the core philosophies of choice, continuity, and connection, we are announcing two strategic terminology updates and introducing one pivotal new concept to the project.

Previous Concept: Silver Communialism (as a standalone concept) Updated Concept: The Dual Economy (with Capitalism and Silver Communialism as co-existing sub-economies)

The Vision Behind the Change: We have elevated our structural approach by introducing the Dual Economy as the overarching framework of the Sim Eternal City. This model positions the Land City’s high-paced Capitalism and the Floating City’s care-focused "Silver Communialism" as two distinct, yet entirely symbiotic, sub-economies.

Why This Matters: This shift establishes a vital narrative of contrast, free will, and bidirectional mobility. It proves that these two systems are not competing forces, but complementary environments that citizens can navigate based on their needs. By emphasizing the power of choice, the Dual Economy shows that individuals can fluidly transition from a growth-driven, capitalist lifestyle into a time-rich, care-focused communal one.

Crucially, this framework highlights that moving to the Floating City is not a permanent, one-way trip. Citizens retain the agency to transition back to the capitalist economy of the Land City if their life stage, health, or personal desires change.

Previous Term: Life Tree System Updated Term: Life Tree Nexus

The Vision Behind the Change: The digital memory and archiving architecture of our framework is one of its most profound elements. To honor this, we have renamed this infrastructure from the "Life Tree System" to the Life Tree Nexus.

Why This Matters: The word "System" often carries a cold, mechanical, and purely technical connotation. Our memory infrastructure is anything but that. "Nexus" translates to a vital, central gathering point, giving the architecture an organic, emotional, and highly connective identity.

This new name perfectly captures the emotional and architectural weight of the technology. The Life Tree Nexus is not just a database; it is the living bridge between physical and digital memory, between the departed and the living, and between the Land City and the Floating City.

New Concept: No Stone Tombstone (Next-Generation Death Care Infrastructure)

The Vision Behind the Concept: Traditional cemeteries permanently consume valuable land and are increasingly incompatible with dense, climate-vulnerable urban environments. No Stone Tombstone is our core solution to this crisis. It replaces the heavy, space-consuming logic of physical graves with a light, mobile, and distributed memorial ecosystem comprised of floating memorial zones, urban kiosks, and mobile ceremony vehicles.

Why This Matters: This concept radically shifts death care from permanent physical occupation to managed temporal and digital continuity. Instead of infinitely expanding physical graves, memory is thoughtfully transitioned into the Life Tree Nexus over time. By moving the weight of memorialization off the land, cities can gradually reclaim legacy cemetery spaces for urgent civic needs, such as public housing. It transforms death care from a static spatial burden into an adaptive, sustainable, and memory-generating urban infrastructure.
